As seen in FIG. 4, the electrical switch SW1 is disposed in a first internal space S1 of the base member 12 at the pommel portion 12P. That is, the electrical switch SW1 is disposed at the pommel portion 12P. The electrical switch SW2 is disposed in a second internal space S2 of the additional operating member 34. Accordingly, the electrical switch SW1 is disposed at the base member 12, and the electrical switch SW2 is disposed at the additional operating member 34.

From another point of view, the electrical switch SW1 is disposed in the upper side US, and the electrical switch SW2 is disposed in the lower side LS. The electrical switch SW1 is disposed closer to the proximal portion 14A than to the distal portion 14B, and the electrical switch SW2 is disposed closer to the distal portion 14B than to the proximal portion 14A.

The electrical switches SW1 and SW2 are configured to be operated by a user. Specifically, as seen in FIG. 4, a button or a switching member of the first electrical switch SW1 protrudes from the base member 12. A user can operate the first electrical switch SW1 by pushing the button of the first electrical switch SW1 or shifting the switching member of the first electrical switch SW1. Pushing the button of the first electrical switch SW1 or shifting the switching member of the first electrical switch SW1 can be referred to as a first input operation.

As seen in FIG. 5, when the additional operating member 34 is pushed toward the second side wall 40 by a user, the additional operating member 34 pivots relative to the operating member 14 about the second pivot axis A2 toward the operated position P22. Such pivotal movement of the additional operating member 34 relative to the operating member 14 can be referred to as a second input operation. The electrical switch SW2 is configured to be activated by the receiving portion 41 of the operating member 14 in response to the second input operation. The second electrical switch SW2 is configured to receive the second input operation from a user to generate a second control signal SG2 in response to the second input operation.

As described above, at least one of the electrical switches SW1 and SW2, the wireless communicator WC1, the informing device INF1, the communication controller CC1, the power supply PS1 may be disposed at a different position from a position described in the above embodiment. FIG. 7 shows possible positions where at least one of at least one of the electrical switches SW1 and SW2, the wireless communicator WC1, the informing device INF1, the communication controller CC1, the power supply PS1 may be disposed.

As seen in FIG. 7, the base member 12 includes the first internal space S1 and a third internal space S3. The third internal space S3 is disposed over the hydraulic unit 22 at the grip portion 12G when viewed from the first direction D1 in the mounting state of the bicycle operating device 10. The operating member 14 includes a fourth internal space S4, a fifth internal space S5, and sixth internal space S6. The fourth internal space S4 is disposed near the proximal portion 14A. The fifth internal space S5 is disposed at the receiving portion 41. The sixth internal space S6 is disposed near the distal portion 14B. Specifically, the fourth internal space S4 is disposed closer to the proximal portion 14A than to the distal portion 14B. The fifth internal space S5 overlaps with the second internal space S2 that the additional operating member 34 includes when viewed from the first direction D1. The sixth internal space S6 is closer to the distal portion 14B than to the proximal portion 14A.

The first internal space S1, the third internal space S3, and the fourth internal space S4 are disposed above at least part of the hydraulic unit 22 when viewed from the first direction D1 in the mounting state of the bicycle operating device 10. That is, at least part of the hydraulic unit 22 is disposed below each of the first internal space S1, the third internal space S3, and the fourth internal space S4. The first internal space S1, the third internal space S3, and the fourth internal space S4 are disposed farther from the free end 14FE of the operating member 14 than at least part of the hydraulic unit 22 when viewed from the first direction D1. That is, at least part of the hydraulic unit 22 is disposed closer to the free end 14FE of the operating member 14 than each of the first internal space S1, the third internal space S3, and the fourth internal space S4 when viewed from the first direction D1. The first internal space S1, the third internal space S3, and the fourth internal space S4 are disposed in the upper side US.

Conversely, the second internal space S2, the fifth internal space S5, and the sixth internal space S6 are disposed below a whole of the hydraulic unit 22 when viewed from the first direction D1 in the mounting state of the bicycle operating device 10. The second internal space S2, the fifth internal space S5, and the sixth internal space S6 are disposed closer to the free end 14FE of the operating member 14 than at least part of the hydraulic unit 22 when viewed from the first direction D1. The second internal space S2, the fifth internal space S5, and the sixth internal space S6 are disposed in the lower side LS.

In the bicycle operating device 10 illustrated in FIG. 7, at least one of the wireless communicator WC1 and the power supply PS1 is disposed in at least one of the first internal space S1, the third internal space S3, and the fourth internal space S4. In a case where at least one power supply (e.g. the power supply PS1) is disposed in at least one of the first internal space S1, the third internal space S3, and the fourth internal space S4, as described in the first embodiment, any wireless communicator (e.g. the wireless communicator WC1) may be disposed in any of the first to sixth internal spaces S1 to S6. Further, in a case where at least one wireless communicator (e.g. the wireless communicator WC1) is disposed in at least one of the first internal space S1, the third internal space S3, and the fourth internal space S4 any power supply (e.g. the power supply PS1) may be disposed in any of the first to sixth internal spaces S1 to S6.

In a case where the wireless communicator WC1 is disposed at the base member 12 (e.g. in the first internal space S1 or in the third internal space S3), the wireless communicator WC1 is preferably disposed to face toward the transverse center plane CP 2 (see FIG. 2). FIGS. 8 and 9 illustrate an example of the bicycle operating device 10 in which the wireless communicator WC1 is disposed in the third internal space S3. Specifically, FIG. 8 is a cross-sectional view of the example of the bicycle operating device 10 taken along line VIII-VIII of FIG. 7. FIG. 9 is a top view of the example of the bicycle operating device 10 as seen from the above in the mounting state of the bicycle operating device 10. In FIGS. 8 and 9, the power supply PS1 is also disposed in the third internal space S3, but the power supply PS1 may be disposed in one of the first, second, and fourth to sixth internal spaces S1, S2, and S4 to S6.

As seen in FIGS. 8 and 9, the first direction D1 is a bilateral direction including a first unilateral direction D1 (e.g. the leftward direction D1) and a second unilateral direction Dri (e.g. the rightward direction Dri). The second unilateral direction Dri is a reverse direction of the first unilateral direction D1. The base member 12 includes a first lateral surface LS1 and a second lateral surface LS2. The first lateral surface LS1 faces toward the first unilateral direction D1. The second lateral surface LS2 faces toward the second unilateral direction Dri. The first lateral surface LS1 is closer to the transverse center plane CP than the second lateral surface LS2 in the first direction D1. Preferably, the wireless communicator WC1 is disposed between the first lateral surface LS1 and the second lateral surface LS2 in the first direction D1. The first lateral surface LS1 is closer to the wireless communicator WC1 than the second lateral surface LS2 in the first direction D1.

Further, as seen in FIGS. 7 to 9, at least part of the hydraulic unit 22 overlaps with at least one of the wireless communicator WC1 and the power supply PS1 when viewed from the above in the mounting state of the bicycle operating device 10. Similarly, at least part of the hydraulic unit 22 overlaps with at least one of the wireless communicator WC1 and the power supply PS1 when viewed from a handle tangential direction HTD parallel to the clamp center axis CCA. At least part of the hydraulic unit 22 overlaps with at least one of the wireless communicator WC1 and the power supply PS1 when viewed from a hydraulic unit based vertical direction HVD perpendicular to the first pivot axis A1 and the hydraulic unit center axis HCA. Accordingly, it is possible to make at least one of the base member 12 and the operating member 14 thin in the first direction D1. Therefore, a user can easily grip at least one of the base member 12 and the operating member 14.

In a case where the wireless communicator WC1 is disposed at the operating member 14, the wireless communicator WC1 is preferably disposed in the sixth internal space S6, because the sixth internal space S6 is closer to the additional component BC2 than the fourth and fifth internal spaces S4 and S5 to improve wireless communication performance. In this case, as described above, at least one power supply (e.g. the power supply PS1) is disposed in at least one of the first internal space S1, the third internal space S3, and the fourth internal space S4 such that the at least part of the hydraulic unit 22 is disposed below the power supply PS1 in the mounting state of the bicycle operating device 10.

The communication controller CC1 may be disposed in a different internal space (one of S2 to S6) from the first internal space S1. In a case where the bicycle operating device 10 comprises the plurality of communication controllers, plurality of communication controllers may be disposed in at least one of the first to sixth internal spaces S1 to S6. Further, at least one of the plurality of the communication controllers (e.g. the communication controller CC1) may be integrated into the wireless communicator WC1 as a single unit.

At least one of the electrical switches SW1 and SW2 may be disposed in at least one of the internal spaces S3 to S6 which are different from the first and second internal spaces S1 and S2. For example, the electrical switch SW2 may be disposed in the fifth internal space S5 of the receiving portion 41 in place of the second internal space S2. In this case, the electrical switch SW2 overlaps with the additional operating member 34 when viewed from the first direction D1. A button of the second electrical switch SW2 protrudes from the receiving portion 41. That is, the electrical switch SW2 is disposed to face the additional operating member 34 in the first direction D1. In this structure, the electrical switch SW2 is configured to be activated by the additional operating member 34 in response to the second input operation, which is described above.

Further, in a case where the power supply PS1 generates electric energy caused by the press of at least one of the electrical switches SW1 and SW2, the at least one of the electrical switches SW1 and SW2 may preferably be integrated into the power supply PS1. Alternatively, the at least one of the electrical switches SW1 and SW2 may preferably be disposed in an internal space in which the power supply PS1 is disposed.

The informing device INF1 is mounted to one of the base member 12, the operating member 14 and the additional operating member 34. In the illustrated embodiment, the informing device INF1 is mounted to the additional operating member 34. The informing device INF1 can be also mounted to one of the base member 12 and the operating member 14 if needed and/or desired. The informing device INF1 may be disposed in a different internal space (one of S1, S3 to S6) from the second internal space S2. Further, the informing device INF1 may be disposed in an apparatus mounted to the bicycle handlebar 2 which is different from the bicycle operating device 10 (e.g. a cycle computer). In a case where the bicycle operating device 10 comprises a plurality of informing devices, the plurality of informing devices may be disposed in at least one of the first to sixth internal spaces S1 to S6.

In a case where structures of the bicycle operating device 10 is applied to the left control device 11 which is shown in FIG. 2, the left control device 11 has substantially the same constructions as those of bicycle operating device 10, except that they are mirror images of each other, they will not be described and/or illustrated in detail here for the sake of brevity.

Second Embodiment

A bicycle operating device 110 in accordance with a second embodiment will be described below referring to FIGS. 10 and 11. The bicycle operating device 110 has the same configuration as the bicycle operating device 10 except for a position of the hydraulic unit 22, a shape of a third internal space S3A in the base member 12, a positional relationship between a first internal space S1A and the hydraulic unit 22, a positional relationship between the third internal space S3A and the hydraulic unit 22, and a positional relationship between a fourth internal space S4A and the hydraulic unit 22. Thus, elements having substantially the same function as those in the first embodiment will be numbered the same here, and will not be described and/or illustrated again in detail here for the sake of brevity.

In the second embodiment, the hydraulic unit 22 is disposed under the pommel portion 12P in the base member 12 when viewed from the first direction D1 in the mounting state of the bicycle operating device 110. The hydraulic unit 22 is disposed over the operating member 14 when viewed from the first direction D1 in the mounting state of the bicycle operating device 110. At least part of the hydraulic unit 22 is disposed above the first pivot axis A1 when viewed from the first direction D1 in the mounting state of the bicycle operating device 110. Specifically, at least one of a whole of the cylinder bore 24, a whole of the piston 26, and a whole of the reservoir tank 32 is disposed above the first pivot axis A1 when viewed from the first direction D1 in the mounting state of the bicycle operating device 110. More specifically, the whole of the cylinder bore 24, the whole of the piston 26, and the whole of the reservoir tank 32 are disposed above the first pivot axis A1 when viewed from the first direction D1 in the mounting state of the bicycle operating device 110.

Further, at least part of the hydraulic unit 22 is disposed closer to the second end 12B than the first pivot axis A1 when viewed from the first direction D1 parallel to the first pivot axis A1. Specifically, at least one of the cylinder bore 24, the piston 26, and the reservoir tank 32 is at least partly disposed closer to the second end 12B than the first pivot axis A1 when viewed from the first direction D1. More specifically, at least one of the whole of the cylinder bore 24, the whole of the piston 26, and the whole of the reservoir tank 32 is disposed closer to the second end 12B than the first pivot axis A1 when viewed from the first direction D1. An outlet port P2 of the hydraulic unit 22 is closer to the second end 12B than the piston 26 when viewed from the first direction D1.

The first internal space S1A is disposed over at least part of the hydraulic unit 22 when viewed from the first direction D1 in the mounting state of the bicycle operating device 110. That is, at least part of the hydraulic unit 22 is disposed below the first internal space S1A. The third internal space S3A is shaped differently from the third internal space S3 in the first embodiment such that at least part of the hydraulic unit 22 is disposed below the third internal space S3A. The fourth internal space S4A is disposed below the whole of the hydraulic unit 22 when viewed from the first direction D1 in the mounting state of the bicycle operating device 110.

Accordingly, the first internal space S1A and the third internal space S3A are disposed farther from the free end 14FE of the operating member 14 than at least part of the hydraulic unit 22 when viewed from the first direction D1. That is, at least part of the hydraulic unit 22 is disposed closer to the free end 14FE of the operating member 14 than each of the first internal space S1A and the third internal space S3A when viewed from the first direction D1. Further, the fourth internal space S4A is disposed closer to the free end 14FE of the operating member 14 than at least part of the hydraulic unit 22 when viewed from the first direction D1. The first internal space S1A and the third internal space S3A are disposed in the upper side US. Conversely, the fourth internal space S4A is disposed in the lower side LS.

Therefore, in the second embodiment, at least one of the wireless communicator WC1 and the power supply PS1 is disposed in at least one of the first internal space S1A and the third internal space S3A. In a case where at least one power supply (e.g. the power supply PS1) is disposed in at least one of the first internal space S1A and the third internal space S3A, any wireless communicator (e.g. the wireless communicator WC1) may be disposed in any of the first to sixth internal spaces S1A to S6. Conversely, in a case where at least one wireless communicator (e.g. the wireless communicator WC1) is disposed in at least one of the first internal space S1A and the third internal space S3A, any power supply (e.g. the power supply PS1) may be disposed in any of the first to sixth internal spaces S1A to S6. Other features are the same as those in the first embodiment.

Third Embodiment

A bicycle operating device 210 in accordance with a third embodiment will be described below referring to FIGS. 12 and 13. The bicycle operating device 210 has the same configuration as the bicycle operating device 10 except for a hydraulic unit 122, a position of the first pivot shaft 20, a pivot pin 142, an operating member 114, an additional operating member 134, a shape of a third internal space S3B in the base member 12, a shape of a fourth internal space S4B in the operating member 114, a positional relationship between a first internal space S1B and the hydraulic unit 122, and a positional relationship between the third internal space S3B and the hydraulic unit 122. Thus, elements having substantially the same function as those in the above embodiments will be numbered the same here, and will not be described and/or illustrated again in detail here for the sake of brevity.

As seen in FIGS. 12 and 13, the bicycle operating device 210 in the third embodiment includes an operating member 114 which includes the hydraulic unit 122. In this embodiment, the first pivot axis A1 (the first pivot shaft 20) is arranged at a front portion of the operating member 114 when viewed from the first direction D1 in the mounting state of the bicycle operating device 210. The first pivot axis A1 is arranged closer to the second end 12B than to the pommel portion 12P when viewed from the first direction D1. As seen in FIG. 13, the hydraulic unit 122 comprises a cylinder bore 124 and the piston 26. The hydraulic unit 122 comprises a reservoir tank 32 connected to the cylinder bore 124. As seen in FIG. 13, the cylinder bore 124 is shaped as a hole in the operating member 114. However, the cylinder bore 124 may be defined by a hydraulic cylinder which is provided in the operating member 114 and which is a different member from the operating member 114. Further, the reservoir tank 32 may be integrated into the cylinder bore 124.

The hydraulic unit 122 is disposed behind the first pivot shaft 20 when viewed from the first direction D1 in the mounting state of the bicycle operating device 210. That is, at least part of the hydraulic unit 122 is disposed closer to the first end 12A than the first pivot axis A1 when viewed from the first direction D1. Specifically, a whole of the hydraulic unit 122 is disposed closer to the first end 12A than the first pivot axis A1 when viewed from the first direction D1. The first pivot axis A1 is disposed closer to the second end 12B than at least part of the hydraulic unit 122.

At least part of the hydraulic unit 122 is disposed above the first pivot axis A1 when viewed from the first direction D1 in the mounting state of the bicycle operating device 210. Specifically, in the illustrated embodiment, a part of the connecting rod 30 is disposed above the first pivot axis A1 when viewed from the first direction D1 in the mounting state of the bicycle operating device 210. However, another part of the hydraulic unit 122 may be disposed above the first pivot axis A1.

In the third embodiment, the base member 12 includes an operating member actuating surface 46 under the first internal space S1B. The operating member actuating surface 46 pushes a top end 31 of the connecting rod 30 toward the distal portion 14B of the operating member 114 when the operating member 114 is operated to move from the rest position P11 toward the operated position P12. An outlet port P3 of the hydraulic unit 122 is disposed closer to the distal portion 14B of the operating member 114 than the piston 26.

In the illustrated embodiment, the additional operating member 134 is movably coupled to the base member 12. The additional operating member 134 does not overlap with the operating member 114 when viewed from the first direction D1. Accordingly, the operating member 114 does not include the receiving portion 41 and the fifth internal space S5.

As seen in FIG. 13, the additional operating member 134 is pivotally mounted to the base member 12 via a rotational mechanism 135. The additional operating member 134 is rotatable about a third pivot axis A3 which is parallel to the first pivot axis A1. The additional operating member 134 is rotatable about the third pivot axis A3 in a fourth movable direction MD4 to accommodate the pivoting of the operating member 114. In this embodiment, the fourth movable direction MD4 is a circumferential direction defined about the third pivot axis A3. The bicycle operating device 210 includes a pivot pin 142 defining the third pivot axis A3. The pivot pin 142 is secured to the rotational mechanism 135. The additional operating member 134 is pivotally mounted to the rotational mechanism 135 via the pivot pin 142.

The rotational mechanism 135 is pivotally mounted to the base member 12 about a fourth pivot axis A4 which is non-parallel to the first pivot axis A1. Accordingly, the additional operating member 134 is rotatable about a fourth pivot axis A4. The rotational mechanism 135 may have the same structure as a structure which the additional operating member 34 and the electrical switch SW2 in the first embodiment constitute and which is illustrated in FIG. 5. In a case where the rotational mechanism 135 may have the same structure as a structure which the additional operating member 34 and the electrical switch SW2 in the first embodiment constitute, the electrical switch SW2 in the rotational mechanism 135 is electrically connected to the wireless communicator WC1. Alternatively, the rotational mechanism 135 may have a rotational structure that a conventional shift unit has. For example, the rotational mechanism 135 may have a gear rotatable about the fourth pivot axis A4, a latch to position a rotational angle of the gear, and a rotation sensor to detect the rotation angle of the gear. The rotational mechanism 135 may further include a biasing member like the second biasing member 44 to bias the additional operating member 134 toward a specific position (e.g. a rest position or an original position).

When the additional operating member 134 is pushed by a user substantially along the first direction D1 which is parallel to the third pivot axis A3, the additional operating member 134 pivots relative to the base member 12 about the fourth pivot axis A4 toward an operated position which is not shown in the drawings. Such pivotal movement of the additional operating member 134 relative to the base member 12 can be referred to as the second input operation. The rotational mechanism 135 is configured to receive the second input operation from a user to generate a second control signal SG2 in response to the second input operation.

As seen in FIG. 13, the first internal space S1B is disposed over at least part of the hydraulic unit 122 when viewed from the first direction D1 in the mounting state of the bicycle operating device 210. That is, at least part of the hydraulic unit 122 is disposed below the first internal space S1B. The third internal space S3B is shaped differently from the third internal space S3 in the first embodiment such that at least part of the hydraulic unit 122 is disposed below the third internal space S3B. The fourth internal space S4B is shaped differently from the fourth internal space S4 in the first embodiment such that at least part of the hydraulic unit 122 is disposed below the fourth internal space S4B. The fourth internal space S4B is disposed closer to the first pivot axis A1 than the hydraulic unit 122 when viewed from the first direction D1. The fourth internal space S4B is disposed closer to the proximal portion 14A than to the distal portion 14B.

Accordingly, the first internal space S1B, the third internal space S3B, and the fourth internal space S4B are disposed farther from the free end 14FE of the operating member 114 than at least part of the hydraulic unit 122 when viewed from the first direction D1. That is, at least part of the hydraulic unit 122 is disposed closer to the free end 14FE of the operating member 114 than each of the first internal space S1B, the third internal space S3B, and the fourth internal space S4B when viewed from the first direction D1. Further, the second internal space S2 and the sixth internal space S6 are disposed closer to the free end 14FE of the operating member 114 than at least part of the hydraulic unit 122 when viewed from the first direction D1.

Therefore, in the third embodiment, at least one of the wireless communicator WC1 and the power supply PS1 is disposed in at least one of the first internal space S1B, the third internal space S3B, and the fourth internal space S4B. In a case where at least one power supply (e.g. the power supply PS1) is disposed in at least one of the first internal space S1B, the third internal space S3B, and the fourth internal space S4B, any wireless communicator (e.g. the wireless communicator WC1) may be disposed in any of the first to fourth and the sixth internal spaces S1B to S4B and S6. Conversely, in a case where at least one wireless communicator (e.g. the wireless communicator WC1) is disposed in at least one of the first internal space S1B, the third internal space S3B, and the fourth internal space S4B, any power supply (e.g. the power supply PS1) may be disposed in any of the first to fourth and the sixth internal spaces S1B to S4B and S6. Other features are the same as those in the first embodiment.
